摘　　要：通过数值模拟轧辊复合铸造法的温度场，得到了使其复合层与辊芯良好结合的工艺参数。采用控制容积法和分段直线拟合曲线，提高了数值模拟精度，提出了连续铸造轧辊复合层界面良好熔合的判据。采用优选法，模拟反推工艺，获得轧辊复合层连续铸造法生产装置的总体设计方案。模拟得到生产良好复合轧辊的必备生产工艺条件，从理论上解决了漏钢、拉拔不出、界面互熔太多、界面熔合不良的问题。The methods of control volume and straight fitting curve are used for computer simulation of continuous pouring process for roll cladding,A criterion for good roll cladding in continuous pouring process is given,Several methods are used for simulation in order to select the optimum technique。The general design of contin-uous pouring process for roll cladding is gotten, Using the simulation the techniques can be obtained such as good roll cladding,bleed-out,seizing-up,overmelt or rack of fusion.
